Tuesday, December 9. 2014This blog has moved!Please note that I won't be updating this blog anymore. I will keep the content around for the time being, but future posts will only appear on the new site. I tried to articulate my reasons for doing so in my post Why the switch to a new blog? Wednesday, November 13. 2013Summarizing my upcoming and past conferences and speaking engagementsThis year's conference season is coming to an end for me soon – I have three more events to go before I can enjoy the Christmas holidays: On 2013-11-20, I'll be at the DOAG Konferenz in Nuremberg (Germany), where I will talk about the following topics (in German):
I've also submitted a proposal for an "Unconference" (or BOF) about Oracle Linux - this will take place on the same day, at 12:00-13:00. From Nuremberg I will travel directly to Munich, where I will speak about Oracle Linux at a Private Cloud mit Oracle Linux und Oracle VM Seminar on Thursday, 2013-11-21. If you would like to learn more about how to set up and manage your private cloud infrastructure using Oracle Linux, Oracle VM and Oracle Enterprise Manager, this event gives you an opportunity to talk to customers who share their experiences and experts that can provide additional background information. This is a free event, registration via the event web site is required. Early in December (2013-12-02/2013-12-03), I'll be attending the UKOUG Tech Conference in Manchester (UK) speaking about the following topic:
Here's a short recap of some past events I attended earlier this year: On 2013-08-24/2013-08-25 I attended FrOSCon 8 in St. Augustin (Germany). Oracle was a silver sponsor and exhibitor — I was there to represent Oracle Linux at our booth. It was really nice to meet many people that I had not seen for quite a while. FrOSCon was well organized (as usual), the only bummer was that the weather did not cooperate and the social event could not take place outside. 2013-09-22/2013-09-25 - Oracle OpenWorld 2013 - San Francisco (US). In addition to attending numerous meetings with customers, I also contributed to the event with the following sessions:

Friday, September 2. 2011What have I been up to lately?Despite my best intentions, I haven't posted on this blog for a while, which is a shame! I've become busy writing on so many other places since I moved into my new role in the Oracle Linux product management team in April. I've learned a lot and I am feeling quite at home here! The team is excellent and very nice to work with — I am slowly getting the "Big Picture". But even though I've been neglecting this blog, there are a lot of things that are publicly visible and document some of my activites: I've created two podcasts for the Oracle Linux podcasts: In addition to working the @ORCL_Linux Twitter account and FaceBook page, I've been blogging on the Oracle Linux blog:
Check out my followup blog post on what I'm up to in the coming weeks and months! Thursday, June 16. 2011Back in Linux landIt's been a while since my last post on this blog; I definitely need to get back into the habit! One of the reasons for my radio silence was that I switched roles here at Oracle. After having been with the MySQL team for 9 years, I felt it was time for a change. Fortunately I did not have to look far – I'm now a member of the Oracle Linux product management team and I am having a lot of fun there. However, I realized that while I was an active Linux user on the desktop, quite a lot has happened on the enterprise and data center side of things. Linux has really come a long way and I am glad to be back in this field, drinking from the firehose and learning a lot about recent developments and technologies. For me, this is kind of going "back to my roots", as I have been deeply involved with Linux at SuSE before I joined MySQL in 2002. Anyway, I'm still alive and you can expect to hear more about Linux and less about MySQL from me on this blog in the future. I also started writing for the official Oracle Linux Blog as well as the OTN Garage blog – watch these spaces for future posts from me, too. In addition to that, my travel schedule is also filling up again: at the end of this month I'll be speaking at the fisl12 conference in Brasil and Oracle OpenWorld in San Francisco later this year. I also submitted talk proposals to the DOAG conference and the UKOUG conference. Looking forward to it! Monday, November 15. 2010Back from Lisbon, off to NurembergYesterday afternoon I returned from the SAPO CodeBits 2010 conference, which took place in Lisbon, Portugal. Just like the previous year, CodeBits has been a great conference to be at and I am grateful for having been selected for participation. Thursday, the first conference day was quite a busy one for me — I gave two presentations in a row: Afterwards, I also participated in a panel discussion about "To SQL or not to SQL", together with representatives from other open source databases (@fdmanana from CouchDB, @antirez from Redis and @bpedro for PostgreSQL). It was an interesting but somewhat slow discussion and the overall conclusion is still the same: there's more than one tool for a given job, choose carefully what your requirements are and don't just blindly believe the hype.On Friday, I had some more time to attend other people's presentations. In the evening I took part in another panel discussion about Physical Computing. I also had the "opportunity" to try one of the Nuclear Tacos (Video) they served — I have never had something that hot before. Ouch! Fortunately my tastebuds recovered in time for the speaker's dinner, which took place later that evening. We went to a Rodizio restaurant nearby, the food was plenty and delicious! Saturday was a pretty low activity day for me. I spent some time in the DIY corner, doing some Arduino hacking. Later that day I attended the project presentations and the closing keynote. Unfortunately a majority of the content was in Portuguese, so I only got parts of the content. But it was still fun! I've published my pictures of CodeBits on Flickr, I hope you enjoy them Later today, I will be travelling to the DOAG Conference 2010 in Nuremberg, Germany. I'll be giving two talks (in German) there on Wednesday, 17th: I already received my speaker badge for this conference (see the picture below). Cool idea: you can use the public transport facilities (Buses, Trams) for free, by presenting this card!![]() There will also be a MySQL Community Meetup on Tuesday, 19:00 at the Press Center of the Congress Center East. If you're around, you're more than welcome to join us there! Next up in the conference schedule for this year is the UKOUG Conference in Birmingham, UK (Nov. 29th - Dec. 1st). We helped them with setting up a MySQL session stream, and they've created an interesting lineup of talks. I'll be speaking about Making MySQL Administration a Breeze - A Look Into a MySQL DBA's Toolchest. See you there!

Sunday, February 22. 2009Site is (almost) back...Sorry for the downtime of this site - until around a week ago I hosted my home page on a trusty Genesi Pegasos II system (powered by a PowerPC G4 Processor clocked at 1GHz, using Debian 4.0 PPC with 512 MB of RAM), serving these pages from my home DSL connection. Unfortunately this system provided no means of redundancy - the hard disk drive died. Luckily I perform frequent backups, so I moved most parts of the site to a shared hosting space now - the picture gallery is unfortunately too big to fit into the space that I have there. I'll try to move the pictures into my Flickr account instead, but this will take some time. Note that the primary domain name of this site is now lenzg.net - lenzg.org, (the domain that I tried to promote as the official domain for my site) used to redirect to the home machine at lenz.homelinux.org. Both now redirect to the new address instead. I've initiated the move of the lenzg.org domain to the other provider as well, so soon this site will be available from both the .org and .net domain. Please don't link to lenz.homelinux.org anymore, as that site will eventually go out of service. Until then, a small openSUSE Linux box (Intel PIII, 500 MHz, 192 MB of RAM) running lighttpd will perform the URL redirection.

Friday, July 11. 2008mylvmbackup 0.9 has been releasedI am happy to announce that a new version (0.9) of mylvmbackup has been released. This is the first release since the source code has been moved from Subversion to Bazaar and is now hosted on Launchpad.net. I would like to thank Robin H. Johnson and Patrick Hahn for providing the patches that contributed to this new release! mylvmbackup is a tool for quickly creating backups of MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, makes an LVM snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds. From the ChangeLog:
You can download a source tarball or RPM from the project home page. Additional packages for various Linux distributions can be obtained from the openSUSE Build Service. Packages for Gentoo and Debian should appear shortly, too. Enjoy! Please let me know how mylvmbackup works for you, either by posting to our mailing list or by submitting a bug report. Thanks!

Wednesday, July 2. 2008Gallery updates and new cameraLast weekend I finally found some time to upload pictures that I had taken during various events that I attended in the past few months. So here are my impressions from the following events:
These are probably the last pictures that I have taken with my trusty old Pentax Optio S4 - I just received my new camera, a Canon PowerShot A720 IS. I have just started to toy around with it, but the first results look promising! The Pentax served me well for several years - I've taken 9745 pictures with it. But it had a few deficiencies, particularly the slow startup and flash recharge time and the bad quality of pictures indoors bothered me for quite a while. But it is very small and handy and the metal housing makes it quite sturdy.

Tuesday, June 6. 2006Back from a long weekend
Yesterday was a holiday in Germany (Pentecost), and again the weather was quite miserable, considering that it's June already. Nevertheless I spent some time in the garden, removing all withered flower clusters from the rhododendron bushes - this is called dead-heading and supposedly improves blooming in the following year. I also noticed that one of our bamboo bushes (fargesia nitida) has bloomed, which is a pretty rare case (for some species, this happens only once every 120 years) but unfortunately also means that all bamboos of this species will bloom and die afterwards. I have already seen the same happening in several other gardens around Hamburg and spotted several postings from other bamboo fans in different forums. Looks like it's time to cut it down and dig out the roots.
The long weekend ended with a blast - yesterday I went to a Depeche Mode "Touring the Angel" Open Air Concert which took place in the Weserstadium in Bremen. The event was sold out and around 40.000 people were there to celebrate. I hadn't seen DM performing live before (except for video recordings), even though I am a great fan of them since the early eighties. It was awesome - they played a very good mixture of old and new material, including one of my personal favourites from their early days: "Photographic". It seems that I was lucky with my choice of location right in front of the stage - I did not experience any of the sound problems that many people reported on the german DM website. And the atmosphere there was great, too - people danced, clapped and cheered like mad, including me! And I guess I was also lucky to not have parked close to the stadium - the traffic around the arena came to a grinding halt after the event... All in all I really enjoyed it - too bad it was over way too quickly! Wednesday, May 3. 2006Back online...Monday, March 20. 2006New pictures onlineToday I uploaded a batch of pictures into my gallery and I also re-arranged a number of albums into a separate Conferences and Events collection. The latest additions in there (yes, some should have been uploaded some time ago already!):
Wednesday, March 1. 2006Lost my wisdom...I returned home safely from Brussels on Sunday night. FOSDEM was great fun, I am going to write up my impressions in a separate entry. I wanted to do it on Monday already, but I had an appointment with the dentist in the afternoon who pulled my two upper wisdom teeth. The operation itself was almost pain-free and went very quick. But once the effect of the local anaesthesia faded, the pain was almost unbearable. After a rough night, I decided to take it slow yesterday. I feel better today, but look like a hamster - my cheeks are quite swollen. Time to replace the ice pack.
